As the length of a glass cable grows, the light signal attenuates due to reflection and a. EMI b. RFI c refraction d. friction 90. The _cable is similar to fiber-optic cable in that it is as thin as a hair and transparent. The big differ however, is that this new cable is full of holes. a photonic fiber c thick coaxial b. single-stranded coaxial d. thin coaxial 91. When a light signal inside the cable bounces off the cable wall and back into the cable, this is called a refraction c blinking b. reflection d. friction 92. transmission requires the use of a very thin fiber optic cable and a very focused light source, such as a laser a Multimode c. Single-mode b. Reflection d. Refraction 93. 94. transmission uses a slightly thicker fiber cable and an unfocused light source, such as an LED a Multimode c. Single-mode b. Reflection d. Refraction transmission systems transmit tightly focused beams of radio signals from one ground-based microwave transmission antenna to another. a. Satellite c. Downlink b. Cellular d. Terrestrial microwave _ 95 transmission means that to receive and transmit a signal, each antenna must be in sight of the next antenna a Uplink c. Line-of-sight b. Omnidirectional d. Downlink 96. The typical distance between microwave towers is roughly to 30 miles c. 8 b. 6 d. 15 07 transmission systems are similar to terrestrial microwave systems except that the signal travels from a ground station on Earth to a satellite and back to another ground station on Earth. a Satellite microwave c. Downlink b. Cellular d. Terrestrial microwave og The closer a satellite is to the Earth, the shorter the times required to send data to the satellite, that is, to a downlink c. download b. uplink d. send down 00 The transmission time from ground station to satellite and back to ground station is called a propagation delay c. uplink b. downlink d. upload
